It's recommended to set at least "ntsec" to be able to change user context without password. Default is "binmode ntsec tty". Run the following command in the cygwin window to replicate the Windows local user accounts to cygwin:.

Table lists the properties for which you must specify a value in the deployment descriptor. The values of these properties depend on the type of authentication and the location of OpenSSH. For password-based authentication, the user name and password specified in the weblogic-ra. Ensure that there is a Windows user with the same name and password as specified in the weblogic-ra. In addition, the user should have administrative privileges.

For public key authentication, the privateKeyFile parameter must be set to the location of the private key file. Specify diffie-hellman-group1-sha1 or diffie-hellman-group-exchange-sha1.

This is an optional parameter where the user can select the default key exchange protocol for negotiating the session key for encrypting the message. Specify the path to the private key file. Specify socket if the SSH server is inside a firewall. Ensure that the authenticationType property is set to password. If OpenSSH is running inside the firewall, then see the following sections:. For more information, see openssh help or manual. To set up the Oracle FTP Adapter for public key authentication, you must specify the values of the parameters listed in Table in the deployment descriptor.

Ensure that the authenticationType parameter is set to publickey and the transportProvider parameter is set to socket. The privateKeyFile parameters should contain the location of the private key file. A sample list of public key authentication properties and their values is shown in Table The privateKeyFile property contains the location of the private key file.

In the deployment descriptor for Oracle FTP Adapter, also specify the following proxy-related properties:. A sample list with public key authentication properties and proxy properties is shown in Table It contains following sections:.

This is an Oracle File Adapter feature to opaquely copy or move large amount of data, from a source directory on your file system to a destination directory, as attachments.

The read file as attachment feature is available only when the Read File option is chosen. This feature of reading files as attachments is very similar to Opaque translation. However, attachments can be of the order of gigabytes depending on database limitations. The AttachmentApp application and the Attachment project appear in the design area, as shown in Figure Perform the following steps to create an inbound Oracle File Adapter service to read a large file from a local directory:.

These fields must be populated with values only if you are using third-party applications that must read this attachment. The attachment in this use case is finally consumed by an outbound Oracle File Adapter, hence these values are not required. Enter the physical path for the input directory, as shown in Figure and click Next. Drag the small triangle in the BPEL process in the Components area to the drop zone that appears as a green triangle in the AttachmentOut in the External References area.

In the case of variables defined by reference to an element, both the source and the target must be the same element. Copy the attachment. This is an Oracle File Adapter feature that lets you use an invoke activity to retrieve a list of files from a target directory. Perform the following steps to create an outbound Oracle File Adapter service to list the file from a target directory:.

You have to assemble or wire the two components that you have created: BPEL process, and the Outbound adapter reference. Create a variable, MyDir of type xsd:string , as shown in Figure , for later use.

Figure The Expression Builder Dialog. Repeat the same process for the second transformation. Select PoToPo. This use case demonstrates the ability of the Oracle FTP Adapter to perform a mid-process synchronous read operation using an Invoke activity.

This use case illustrates the following adapter functionality:. The process is initiated by the presence of a trigger file appearing in a local directory monitored by the inbound Oracle File Adapter.

The trigger file contains the name of the file to be read by the synchronous read operation. This file name is passed through headers to the adapter.

This can be done using the Properties tab for the Invoke activity. This synchronous read file operation is performed against a remote directory on a FTP server. The result of the read is then transformed and written out to a local directory through the outbound Oracle File Adapter. This section includes the following topics:. Copy the addr1Toaddr2. Click Project Schema Files , trigger. The URL field in the Messages page is populated with the trigger.

Select Synchronous Get File , and click Next. Enter dummy. The Messages page is displayed. You have to assemble or wire the four components that you have created: Inbound adapter service, BPEL process, two Outbound adapter references.

Question : Types of Adapters? Answer : Read is used when Polling is required to be done while SyncRead is used when you need to read the file in between the flow i. Question : What is File Debatching? Answer : When a file contains multiple messages, you can choose to publish messages in a specific number of batches.

This is referred to as debatching. During debatching, the file reader, on restart, proceeds from where it left off in the previous run, thereby avoiding duplicate messages. File debatching is supported for files in XML and native formats. Question : What is File ChunkedRead?
